Arnold get stuck at last bucket when rendering Bifrost cached sims ramdomly

Hello I wonder if this is happenning to someone else , when I do a maya sequence render sometimes but a lot of times Maya get stuck rendering at the very last bucket, it happens in all my computers, doing a batch render seems to fix this issue but not everyone have a Arnold licence to do a batch...

Hello Stephen, I am running the latest version of Arnold, it does stops rendering one part of the fluid but sometimes it stops in empty spaces.. it is very strange... It just stops at 99% done and Maya gets unresponsive!

It happens in all my computers, it all gets fixed if I run a Maya Batch it only happens with the render sequence command!
